Action Replay Pro 64 was basically the cheat code holy grail for N64 back in the day. V3.3 lets you unlock all sorts of wild stuff—think infinite lives in GoldenEye or skipping straight to Bowser in Mario 64. Plug it in, scroll through a massive list of codes (some work better than others, fair warning), and suddenly you’re breezing through levels or breaking the game in ways the devs never intended.

It’s not just about making things easier, though. Some codes reveal hidden test levels or unused character models, which is kinda cool if you’re into digging up gaming secrets. Just don’t expect every code to be perfectly stable—half the fun was seeing which ones would glitch out spectacularly.

If you ever spent hours manually inputting button combos from cheat books, this thing felt like magic.
